I just returned from the Illinois Railway Museum, supposedly the LARGEST railroad museum in the USA, and I wasn't overly impressed. Sure, they have a LOT of locomotives, but NOWHERE can you actually go INTO a cab or even get close to a look inside. Many of the locomotives are rusty and in bad need of repair.
I walked through one LONNNNNGGG building and passed one steam loco after another... LOTS of steam locos, but they just seem to be sitting there, crammed in the building. No upkeep.
The place seemed very un-organized. The gift shop, while large, was sloppy and unorganized. There was a used book store with lots of old back issue railroad & train magazines, but, again, with virtually no organization. If you needed a specific back issue, your only recourse would be just to start looking through EVERYTHING!
Most of the passenger cars were OFF LIMITS to any inside inspection. You just have to be content to view the outside.
And another thing. . . FINDING the museum was relatively easy, but returning back to the main highway was almost impossible. We got lost three or four times. Apparently, the Illinois highway department needs some of the Stimulus money so they can make some badly needed highway signs. We drove on several roads and highways that, for miles and miles, had no signs telling you what highway you were on.
The best part of our vacation was the Railroad Park at Rochelle, Illinois! I spent hours watching the big UP and BNSF locos roar by, and at the same time, met many Railfans from all over the country and world. Rochelle's Railroad Park is definitely worth a trip. And the Butterfly Restaurant in Rochelle cannot be beat!!!
